“…More recently in altricial songbirds, parental vocalisations during incubation have been shown to vary according to the biotic and abiotic context such as parasitic cuckoo presence 11 or ambient temperature 12 , and may accordingly play a role in brood parasitism avoidance 13,14 or heat adaptation 12 . For example, in two species of fairy wrens, nestlings have been found to produce begging calls resembling part of the maternal incubation call, which is thought to allow provisioning parents to discriminate against dissimilarly-sounding cuckoo nestlings 13–15 . Surprisingly however, in spite of this diversity of functions across species, whether parents produce calls specifically to signal to embryos has rarely been questioned.…”

Sound is arguably the external cue most accessible to embryos of many species, and as such may constitute an unrivalled source of early information. Recent evidence shows that prenatal sounds, similarly to maternal effects, may shape developmental trajectories. Establishing whether parental vocalisations are signals directed at embryos, or parental cues on which embryos eavesdrop, can elucidate whether parents or embryos control developmental outcomes. Prenatal exposure to a characteristic heat-related parental call was recently shown to alter zebra finch growth and fitness. Here, we test the ecological context of this behaviour in the wild, and assess the information value and specificity of this vocalisation for an embryonic audience. We show that wild zebra finches also produce this characteristic call, only at high temperatures. In addition, in the lab, we demonstrate experimentally that calling is specifically triggered by high air temperatures, can occur without an embryonic audience, and importantly, is predicted by individuals’ body mass. Overall, our findings reveal a specialised heat vocalisation that enables embryonic eavesdropping, by indicating high ambient temperatures, and parents’ capacity to cope with such conditions. This challenges the traditional view of embryos as passive agents of their development, and opens exciting research avenues on avian adaptation to extreme heat.

“…Embryonic heart rate can be measured non‐invasively using a relatively new device—the Buddy digital egg monitor (Vetronic Services, Devon, UK) (Rivera, Louder, Kleindorfer, Liu, & Hauber, ; Sheldon, McCowan, McDiarmid, & Griffith, ). The acquisition of short‐term heart rate measurements using the digital egg monitor has been used to demonstrate plasticity in embryonic heart rate in response to a range of environmental and social cues (Colombelli‐Négrel, Hauber, & Kleindorfer, ; Du, Ye, et al 2010; Du, Zhao, & Shine, ).…”

Embryonic heart rate predicts prenatal development rate, but is not related to post‐natal growth rate or activity level in the zebra finch (Taeniopygia guttata)

Inter‐individual variation in behaviour has been the focus of much recent work, yet the underlying mechanisms that cause and maintain this variation are unclear. It has been proposed that consistent individual differences in metabolism could be related to inter‐individual variation in behaviour and development throughout life. Here, we tested this idea in the zebra finch (Taeniopygia guttata), by investigating whether embryonic heart rate (a proxy for metabolic rate) is associated with prenatal developmental rates, post‐natal activity levels and post‐natal growth rates. Embryonic heart rate and post‐natal activity level were significantly repeatable throughout an individual's development, such that consistent individual differences in these traits could be distinguished. We detected a significant, negative relationship between embryonic heart rate and incubation duration. However, we did not detect any relationship between embryonic heart rate, post‐natal activity levels or post‐natal growth rates. Our findings are significant because they identify consistent individual differences in embryonic metabolic phenotype and post‐natal traits. However, we were unable to identify any correlation between the pre‐ and post‐natal phenotypes suggesting that either intrinsic metabolic differences do not persist across the developmental boundary of hatching or such differences become obscured by parental or environmental effects after hatching. Our findings raise a number of questions about possible selection on metabolic phenotypes, both before and after hatching, and why developmental trajectories before and after hatching are apparently unlinked.

“…Studies also suggest that chickens are sensitive to auditory effects and the auditory system begins to develop during incubation (TONG et al 2013), and they are also capable of perceiving and processing different frequencies, but this could change among the altricial species (RIVERA et al 2018). Chickens demonstrate considerable complexity.…”

A intensificação do sistema de produção avícola trouxe profundas mudanças no ambiente físico e social das aves domésticas. O manejo dessas aves tem recebido considerável atenção nos últimos anos devido às novas demandas por parte dos consumidores, principalmente aquelas relacionadas ao bem-estar. O comportamento é a maneira como os animais respondem aos diferentes estímulos que encontram em seu ambiente. As expressões comportamentais das aves domésticas e a aplicação desse conhecimento no cuidado dos animais desempenha um papel importante na maximização da eficiência de produção da cadeia avícola. Assim, definir limites éticos e diretrizes para a produção avícola é fundamental para fomentar o desenvolvimento de novas práticas produtivas, e assim garantir qualidade e produtividade sem colocar em risco o bem-estar dos animais. Esta revisão destacará as principais expressões comportamentais das aves domésticas, dentre elas as expressões sociais, alimentares, reprodutivas, além de estereotipias, e identificará as estratégias de adaptação social. Assim, promovera ao leitor e a comunidade científica uma melhor compreensão de assuntos pouco discutidos para assim auxiliar em análises comportamentais.
